How to Install Roms, and resolve Issues on the Xiaomi Mi8 - Xiaomi Mi 8 Guides, News, & Discussion

I am making this post to serve as a All in One Guide for Rom installation or switching to Miui Beta Roms. Happy Flashing!
This post is for people looking for first time Rom flashing instructions, or people wanting to go back to a Miui Rom
__________________________________________________________________________________________________________
I have been told that this post is too long and I agree, so it will be improved upon ASAP ( within a couple of days)
TO BE CLEAR,
If you have unlocked your bootloader, install TWRP and then YOU Must Format Storage
Next flash the Global Rom and flash root.
Boot to system, and go past Google Assistant setup.
Now you can reboot to recovery and dirty flash the EU Beta Rom or my preference the Mi-Globe EU Beta ( more options)
Dirty Flash Beta Rom , then reflash root, reboot to recovery, clear cache and reboot to system
Done
__________________________________________________________________________________________________________
If you are experiencing issues: you are likely dealing with encryption problems that are caused by certain roms.
In addition you need to ensure that you are not only using the correct files needed for your device ( Chinese or Global) You will want to use the most current Vendor and Firmware files.
Go to the first post below this OP for Custom Rom installation steps and to download the Vendor and Firmware files.
THese instructions assume that you have already unlocked your bootloader
⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧ Click Link for unlocking Bootloader ⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧
Two methods for your rom installation
See instruction below for preparing your phone for your very first installation
Flashing TWRP: You can use ADB, Mi-Flash or >>The All in One Tool ( I Recommend the All in One Tool) )
You need to be in Fastboot Mode ( Enter Fastboot by Pressing and holding the volume down and power simultaneously)
Using ADB
1. Install ADB/Fastboot tools on your computer
[*]Enter fastboot mode on phone (hold power and VOL -)
[*]Make sure adb can see and control your device
[*]Run { adb reboot bootloader } - No spaces (before/after)
[*]Run { fastboot devices } to make sure you see your device
[*]Run { fastboot oem device-info } just to reverify your unlock status
[*]Run { fastboot boot recovery_twrp-3.2.3-1-dipper.img}
[*]Reboot back to TWRP ( Press and Hold Volume up and Power button simultaneously) and then begins the installation of your Firmware, Vendor, Root, Your Rom of Choice, and Gapps ( only If needed) and then Magisk 18.1 again. ( Note DM Verity is built into Magisk 18.1)
[*]If you wiped data, your device will now proceed to re-initialize itself as if from the factory
[/LIST]
If you do not own an OTG adapter and a good sized USB drive , buy them and save yourself many hassles
You will save your self a lot of time, especially if you want to fully save a complete Nandroid backup for later re-installation or transfer to your desktop. Thanks to @The War Profiteer for correcting my assumption that the Mi8 has superspeed transfer capability via its usb port ( It does not!)
Regardless using an OTG adapter is still convenient when you are away from your network and need to quickly restore a backup, I have one shaped like a key that I keep with me at all times.
To remove encryption you will always need to format the storage
Not wipe >> choose Wipe > then choose > Format data > > type "yes" to format
Now You Must reboot to Recovery, or the installation may not recognised the formatted data partition
If you see a message that says there is no OS installed are you sure > Don't worry about it, yes, you need to reboot to Recovery
After Formatting and booting to recovery
Install Firmware and Vendor, then install Rom, and whatever else is needed for that installation such as Gapps and Root.
Let's repeat this steps again for Clarity.
Installation of Firmware, Rom, Gapps, Magisk
Boot into TWRP recovery
1. Go to "Wipe" and then to "Advanced Wipe".
2. Mark "Dalvik / ART Cache", "System", "Data" and "Cache".
3. "Swipe to Wipe" and proceed back the main menu.
4. Go to "Install" and install base firmware and vendor if needed. ( See first comment below for files)
5. Select the ROM's zip file and then press "Add more Zips" and select the Gapps zip file ( If needed) , and then the Magisk root file.
6. "Swipe to confirm Flash" and wait
7. After the flashing is finished, just reboot to Recovery, Check Boxes > Reboot to system
Finished!
More about the All in One Tool
The tool is an easy way to resolve a myriad of issues.
It keeps your desktop drivers and adb up to date and provides ADB system wide privileges
See More about all in One tool by clicking unhide
USE @mauronofrio "TOOL ALL IN ONE""
It can be used for removing encryption, installing TWRP, Root, your ROM, Gapps, and even to restore to stock Recovery, or to flash a stock Rom
TOOL ALL IN ONE : https://forum.xda-developers.com/mi-8/development/tool-tool-one-driverstwrpfactory-t3895807
If your device not recognized, there is little doubt that it is a desktop USB driver issue, so ensure that device drivers are installed
You will need to reinstall the Google USB driver, and while you are at it check to make sure adb is up to date.
FYI: The All in One tool can do all of this for you, it's done within the advanced menu section.
You will need to temporarily disable Windows defender for installation.
Typical Custom Rom flashing Pre-Instructions - this is relevant to all non Miui , custom roms.

1. Flash Firmware and vendor, when flashing vendor choose Mount and then check vendor only, then flash.)
2. Flash Force Decrypt, then Flash ROM of choice & OpenGapps ( if not included in Rom)
3. Flash Root, Reboot to Recovery, Reboot to system.
If coming from Oreo ( You must first have Miui Stable installed Version: MIUI 10.0.2.0)
[*] Flash MIUI V10.0.2.0.OEAMIFH global stable Rom DON'T REBOOT
[*]Flash Disable_Dm-Verity_ForceEncrypt Here DON'T REBOOT
[*]Wipe Data,System,Cache Your Data will be lost
[*]Flash Rom of Choice + Gapps
[*]Reboot and Enjoy[/LIST]
If want to go back to Miui
Flash firmware based on last Official Miui install , Flash root ,
Reboot to Twrp Recovery and perform factory reset
Then flash Miui Rom of choice. and Root if wanted
Enjoy
Please Read - Jan 2020 update
Edit: This post was assembled in March of 2019 : It needs some updating which I will do, when I have time and feel like spending it on updating this thread. Disregard versions of Firmware listed on this OP, those suggestions are now irrelevant. Instead follow the advice from the Rom developer. Very often the rom will include the vender and driver firmware ( AKA DFE)
I definitely recommend using the version of TWRP that I linked here: https://forum.xda-developers.com/showpost.php?p=81329605&postcount=366
For additional suggestions, check my next posts, immediately after the OP ( first comments ) and for update information check here:

Update vendor + firmware for custom Rom use
Thanks to user Lurii G from 4PDA, when I first bought the phone I updated my knowledge by following his posts, the following is partly paraphrased from his original posts.
Install updated version of TWRP Recovery for the M8 ( AKA Dipper) : https://dl.twrp.me/dipper/
Update*vendor*using TWRP* :
Global and Chinese Stable Vendor files : https://xiaomifirmwareupdater.com/#stable
Global and Chinese Beta Vendor files : https://xiaomifirmwareupdater.com/#weekly
Certain Roms cause encryption issues and there is no way to resolve installation issues without first decrypting storage and then flashing the Vendor + Firmware files
Download the vendor and firmware either from the links above or my mega link on the OP ( doesn't matter)
If you want to know more about the most up to date vendor versions directly from yshalsager
Go here: Firmware update Sources : https://github.com/XiaomiFirmwareUpdater/firmware_xiaomi_dipper
Note that firmware is not a complete copy of the Miui stock ROM firmware, it is only a package of the most essential drivers, partition images all of which serves as a base for a custom rom.
Be sure to read the OP of any Rom that you plan to install, You may need to change the base firmware depending on what drivers that developer built the rom over. Use at your own risk.
I strongly suggest that you make a nandroid backup prior to making any changes.
I suggest using an OTG drive and flash the following files prior to flashing any AOSP Rom:
AOSP Installation Steps
1. Flash Vendor in this case : FSTAB-EXT4_F2FS-Dipper.zip it is the most current >
2. When installing the vendor file: Be sure that you select Mount and then Vendor , so that you are only flashing to the vendor partition
3. Next Flash Drivers: At the time of writing this post, I am using : 9.3.14 Firmware :
Note you may need a more up to date or older version depending on what Rom you flash. At the time of writing this 9.3.14 is the most recent firmware
4. Flash your Rom of choice ROM
5. Flash Disable_Dm-Verity_ForceEncrypt_v1.4.zip ( FYI: Magisk 18.1 includes DM verity disable)
6. Flash Gapps ( Only if needed )
7. Flash Magisk optional*
8. Reboot* to Recovery ( Check boxes to install TWRP Manager)
9. Reboot to system and setup
Lets Recap :
1. After installing the the vendor, be sure to flash the radio driver ( Firmware) Next you flash the Rom, the disable DM Verity file, Gapps if needed, Root if wanted > Reboot to Recovery, Reboot to system > setup.
2. Some Roms may already include the vendor, if you have a bootloop, try reflashing the vendor file only, and be sure to mount the vendor partition

Thanks a lot mate for the big description, its really helpful. What I do not really understand is , I got a chinese mi8 and doesnr it mean I would enable ARB by installing a vendor of 9.3.14 ?

I quickly pieced together an answer for you, keep in mind that this is not a definitive guide. Give me a couple of days and I will try to expand on it by editing this post with more detailed ARB information. Plus, I will link to here from the OP.
Use any of these steps at your own risk,
I own a global version of the Mi8 and will not personally experience the bricking potential that people with the Chinese version of the Mi8 have to worry about.
Regarding 9.3.14 :
Should be fine if you are using the chinese firmware version, I.E: fw_dipper_miui_MI8_*.zip is Xiaomi Mi 8 (dipper) China firmware >>>> Keep in mind that base firmware is really nothing more than just drivers, and radio bands >>>> Get your correct firmware from here: https://xiaomifirmwareupdater.com/#stable
EDIT : See this post too: https://forum.xda-developers.com/showpost.php?p=78911687&postcount=8
Basic ARB Instructions if you have a Chinese device
First ensure that your phone is correctly unlocked with the Xiaomi Unlocking tool, setup your Miui account and use the Miui Forum app and you will get access to better features and themes while using a Miui OS.
The main issue and thing to beware and afraid of is installing a global rom on a Chinese version of the Mi8 … It seems that it is really only an issue If The Bootloader Is Locked or if you try to relock it.
Do not install Global firmware on a locked device or you will have a definite brick.
Make sure that your phone is linked to your account, this way you have complete control. Personally, If I had a device with a vendors account, I would demand a refund either from the vendor or the website dealer.
To Check ARB
Go to fast boot and type in the code "*fast boot*fastboot getvar anti*" on your CMD.
ARB level is max to 1.
AFAIK: Most roms are Arb=1 or Arb=0 so its apparently safe to install those roms.
To be safe, do not mess with ARB always flash rom using Fastboot method.
Paraphrased Excerpt below from user “YoungChaos” (member of MIUI Device Team) rephrased for clarity in English.
Arb is anti-rollback and it's used for security reasons:
It will deny any attempted installation of older firmware, it used for security purposes to prohibit old exploits. ( So he is saying that once you install base firmware, don’t try to install old bad firmware over top of it.)
Re-locking the bootloader, is another thing to to avoid
To avoid brick you CAN-NOT re-lock bootloader with a global rom on a Chinese Phone.
To avoid ARB issues just flash "official" firmware using fastboot ( Firmware is used in this context as the base drivers.)
If using ADB, you will be alerted you if you are risking ARB or not. The Bootloader has a check to protect you from flashing a lower-arb rom , so it will protect you from bricking your device and It will show you an error and you will understand that you cannot flash it.
This may have been updated to include warnings within TWRP. I install almost everything strictly within TWRP…But I have a global device.
I hope this helps you.
Edit:
I have a theory, I believe that the only thing that make the chinese phone and the Global one different is the Radio drivers ( well specifically the modem, or Non.Hlos.Bin image. and vendor files.
On other phones, you can make a Global phone think its a Chinese phone and vice versa. I am wondering if there is maybe a way to a create a flashable file to get around the risk of bricking a Chinese phone. The only differences that I can see between firmwares is with the modem, outside of that it looks identical. If this can be solved, customer roms could be setup to flash certian firmware based on the device ID. Maybe.

The link that you posted is not working for me, it only goes to Google, with the link in the searchbox.
I found a video for you that should help clarify.
https://www.youtube.com/watch?v=Bf44z8xbKH4
So to answer your question you should be able to flash the Global Weekly, granted that you have followed all of the preliminary steps, also be sure to back up your data with the built in Backup tool. Trust me is makes these updates so much faster and much more convenient.
Watch the 5 minute video to ensure that you have covered all steps.

I recommend USB 3.0 because it's much faster and using at least 32 GB's for easy access to your files and nandroid backups

Mi8 supports USB 2, not 3. It'll have no effect on the performance rather than a placebo.

I am making this all in one guide after seeing the countless posts of people looking for instructions for first time Rom flashing, or dealing with encryption issues caused by some roms. I enjoy helping people. But, I don't want to type this stuff over and over. So this post will help me help them. If this post helps you, you can thank me by helping someone else and clicking thanks. Happy Flashing!
If you have followed everything on this OP and you are simply experiencing a bootloop go to the first comment under the OP for the solution. ( Skip these steps and go there instead)
NOTE: If you have already unlocked the bootloader and flashed TWRP to the recovery partition. But have not yet flashed root or your Custom Rom, the OS your recovery can very likely reset back to the factory recovery >>> UNLESS YOU ROOT THE SYSTEM.. <<<<< Don't worry : Your device is still unlocked. But the recovery can be overwritten by the stock recovery, so be aware.
See the bottom section for preparing your phone for your very first installation > see the first comment for the vendor and driver files
I am providing two methods for your rom installation
You can of course use ADB and flash TWRP .......You just need to be in Fastboot Mode
Alternatively you can use the All in One Tool :
If you are new to flashing I highly recommend using this tool because its easy to use even if you are an ADB guru, it's Quick and Easy period.
Developer Options
Make sure you have enabled the developer tools,
Turned on USB debugging, and authorized your computer on your device “MTP”
Have your files and notes ready, if flashing AOSP don't forget the firmware and vendor files.
If using ADB
Be sure to be in in the correct ADB directory and place needed files within that directory ( If you don't know what this means, it may be better for you to use the All in One tool method instead)
Install ADB/Fastboot tools on your computer
You should already have the unlocked Bootloader and have setup Developer Options
Using ADB Method
Enter fastboot mode on phone (hold power and VOL -)
Make sure adb can see and control your device
Run { adb reboot bootloader } - No spaces (before/after)
Run { fastboot devices } to make sure you see your device
Run { fastboot oem device-info } just to reverify your unlock status
Run { fastboot boot recovery_twrp-3.2.3-1-dipper.img}
Reboot back to TWRP ( Press and Hold Volume up and Power button simultaneously) and then begins the installation of your Firmware, Vendor, Root, Your Rom of Choice, and Gapps ( only If needed) and then Magisk 18.1 again. ( Note DM Verity is built into Magisk 18.1)
If you wiped data, your device will now proceed to re-initialize itself as if from the factory
Side Note - Not really needed just FYI
DM Verity can be enabled or disabled from with fastboot commands
fastboot oem disable_dm_verity
fastboot oem enable_dm_verity
If you do not own an OTG adapter and a good sized USB 3.0 drive , buy them and save yourself many hassles
I recommend USB 3.0 because it's much faster and using at least 32 GB's for easy access to your files and nandroid backups
Concerning your device's storage
When you boot into Twrp you may see a message that asks if you’d like to use TWRP in “Read Only” mode. Read Only mode means TWRP will only exist on your phone until you reboot it.
You Do not want Read only, if you want permanent access to TWRP ( You do)
*****************Important************************ ******************
Ensure that you have TWRP installed permanent by rebooting to Recovery
Ensure that you have TWRP installed as the primary recovery
Always reboot to Recovery and check the boxes to install TWRP when rebooting to recovery
To remove encryption you will always need to format the storage
Not wipe >> choose Wipe > > Format data > > type "yes" to format > > Now You Must reboot to Recovery, or the installation may not recognised the formatted data partition (If you see a message that says there is no OS installed are you sure> Yes, reboot to Recovery))
After Formatting go ahead and install your needed Firmware ( Read Below and the OP of whatever ROM you are using) then install Rom, and whatever else is needed for that installation >>> Enjoy Root: Yes you should absolutely should root for the full custom Rom experience. However, its not always necessary. Plenty of people choose to remove Root after installing their software of choice.
To Reiterate >> Installation of Firmware, Rom, Gapps, Magisk
Boot into TWRP recovery
1. Go to "Wipe" and then to "Advanced Wipe".
2. Mark "Dalvik / ART Cache", "System", "Data" and "Cache".
3. "Swipe to Wipe" and proceed back the main menu.
4. Go to "Install" and install base firmware and vendor if needed. ( See first comment below for files)
5. Select the ROM's zip file and then press "Add more Zips" and select the Gapps zip file ( If needed) , and then the Magisk root file.
6. "Swipe to confirm Flash" and wait
7. After the flashing is finished, just reboot to Recovery, Check Boxes > Reboot to system

Easy Way to so many issues with do this with one tool >>>>Donate to @ Mauronofrio he totally deserves it!
@mauronofrio built this excellent tool for us. It keeps your desktop drivers and adb up to date. Plus it will give ADB system wide privileges. In addition to all of that it is easy to use.
You have encrypted data this tool can solve that issue easily.
The software tool is called: "TOOL ALL IN ONE"" and it's great and will unencrypt your drive.
After you install it, make sure to check for AIT updates.
To Reiterate
* The all is one tool is excellent and you can use it to install everything you want.
* You can use it to unlock the bootloader.
* Remove Encryption
* Install TWRP,
* Install your Rom, Gapps and Magisk etc.
* The tool will also update your existing installation of ADB, Android Drivers, and provide system wide ADB privileges.
Pre Installation Steps
You have unlocked the bootloader and have TWRP installed, plus you can you boot into Recovery Note Firmware will get upgraded over time so use the OP firmware and vendor files that are suggested by the maintainer on the first page of every Rom.
Havoc Pre-Instructions - relevant to all custom roms.
If coming from Miui Pie
Flash Force Decrypt Zip Here
Update firmware & vendor by flashing : Firmware - 9.2.15 - Download HERE + Force Decrypt Zip from step 1. again (just to be sure)
Flash ROM of choice & OpenGapps ( if not included in Rom)
If coming from Oreo ( You must first have Miui Stable installed Version: MIUI 10.0.2.0)

Wow, thanks for pointing that out, it was left there by mistake.
I knew that it could not unlock the bootloader for the Mi8, since the Xiaomi Unlocking tool is needed.
But your All in One Tool can no doubt unlock the bootloader of other devices. A section the guide was copied from my original write up written for the Le Pro 3 almost 2 years ago. .and I thought that I removed all of the Le Pro 3 references and even proofread the post. I facepalm?
I completely missed and apparently left that part in. So thanks for letting me know, I will remove that part ASAP.
Otherwise your tool is amazing, and I hope that we can get more people to use it and then contribute something to you for your hard work, and building such an highly useful and amazing tool.

No, You misread/misunderstood the post, or I didn't explain it well enough to be clear.
I actually only recommended using USB 30 flash drives, because they are much faster than usb 20 flash drives and can take advantage of the high speed offered by the USB C Port.
The reason why USB 3.x drives are better is because you can keep a massive library of files, and more importantly large nandroid backups on the USB drive and as long as backups are stored with the correct folder hierarchy in tact, you can quick restore those backups quickly and from the USB flash drive itself instead of the storage partition.
Next, the USB 2.0 transfer speed is 480 megabits per second (Mbps) while USB 3.0 transfer speed is 4,800 Mbps. This means that USB 3.x is approximately 10 times faster than USB 2.0.
You can take advantage of this speed by using USB 3.0 drives. Plus they are cheap.
I bought 2, 64 GB USB 3.0 and flash drives for $21 a year and a half ago, after getting tired of waiting on transferring 12GB files to and from USB 2.0 drives.
The drives are in fact compatible, I use them in real life, so there is no placebo effect, usb 3.0 is dramatically faster, and the time difference transferring files is large. I am sure that there are plenty of whitepapers out there and videos to prove it., if you have doubts. In fact probably can find info here : USB C : 3.1 Interoperability Testing v0.95 w USB Type-C.pdf , to be able to use "USB C" there are standards in place about power delivery and transfer speed.
EDIT: I embarrassed myself, after spending a hour and a half researching this for myself, I found that the The War Profiteer was indeed correct, the Mi8 does not have Super Speed transfer which for me is I think very unusual to me since I have several other phones in my house with USB 3.0 compatible Usb 3.0 Ports.
This is one of the corners that Xiaomi cut to keep their prices low. So my argument above is moot, and I have no issue admitting my mistake..learned something new! At the end of the day, I would rather have amoled over USB 3.0 speed so no worries.

There were probably an error on your side, at this point I'll consider that you are OK to export your backups/data from your phone over USB 2 connection, I guess. But USB C port does not offer any kind of high speed, Type C is only a different form of an USB port, like door handles. Just a different shape but nothing else.
Nice thread tho, there are a lot of things that I think newbies would learn about.

hello, I have a problem, I can not mount the partition system, I'm with the rom of xiaomi.eu developer version 9.3.14.
When installing the TWRP for the first time if you make the format data, the partition is mounted and works well, but not the partition system, I hope you can help me, greetings from Chile

So after reading all your stuff in this Thread and on other pages I guess that you can still flash n official.global rom on a chinese mi8 AS LONG as you do not lock the bl and you dont downgrade it. That should mean that in theory it should always be possible to update to the newest available version.

Don't worry about choosing mount unless you are installing the vendor file., in that case you only want to install it to the vendor partition and it only matters If you are installing a CAF or AOSP custom rom. You can aleve yourself of confusion by rebooting to recovery after installing vendor and the mount points will automatically reset. Chose factory reset and then install your rom from within TWRP
Most Custom Roms have a script that will choose the correct partition for installation, if there is a problem you will get an installation error 1 or error 7 if the issue is storage encryption.

Thanks for comments and yes this thread is for new people.
Regarding USB C and door handles, I really thought you were joking? You say that are from Uranus, so I thought that you were surely just being hilarious and simply pulling my leg.
Absolutely manufacturers can indeed use the USB C shape, and even implement quick charge technologies and yet cut corners and choose to not implement USB 3 + speed.
According to everything that I read the Mi8 is rated for Quick Charge and one would assume high speed transfers as well.
Sadly No that is not the case, you are absolutely correct and I was completely wrong, I tested the speed and my old LeEco phones are much much faster with USB file transfer speed.
While I still love this phone, Xiaomi did not implement USB 3.X Super Speed Technology. For some reason! It's really disappointing because this USB C port also does not support USB C to HD video, while my Le Pro 3's USB C port does.
Thank you for being persistent. I ended up spending over an hour looking for information to prove my case only to find that I was flat wrong.
Thanks again.

There were probably an error on your side, at this point I'll consider that you are OK to export your backups/data from your phone over USB 2 connection, I guess. But USB C port does not offer any kind of high speed, Type C is only a different form of an USB port, like door handles. Just a different shape but nothing else.
Nice thread tho, there are a lot of things that I think newbies would learn about.

You are right, so slow!
By the way, I off topic... 9.3.14 is a perfect build.

You are welcome.
There are no obvious reason for this, but I'd say its about the cost, perhaps. There are some alternative options to transfer any data over ADB, always. It's way faster than MTP interface or any other software that can be used for this purpose. First of all, transfer over wifi will be the fastest and most convenient way when there's only a USB2 port, which will be done with a companion app that will let you use ADB over wifi. Here's the app I've been using for years for this purpose: https://play.google.com/store/apps/details?id=com.ttxapps.wifiadb
On other conditions that you will not be able to use any app or network interface, like getting stuck on TWRP, it will still allow you to send adb commands.
After getting the recent adb libraries on your computer, all you need will be two commands and the path of the desired file or folder.
adb pull input output
adb push input output
These two commands will provide you way faster file transfer, without root. still, I'd recommend using them over WiFi.
The problem here is that if you will be transferring to a USB device, you won't be able to use them since there will be no adb interface. I guess using terminal emulators with native Linux commands should be fine, just in theory, but haven't tested it yet.
